Celebrity Series of Boston presents “Revelations Celebration Community Workshops,” two free, all-ages, family-friendly events where participants will hear live music and learn dance moves from Alvin Ailey’s iconic work, Revelations, in a fun, welcoming, inclusive environment led by longtime Ailey dancer and master teacher Nasha Thomas, with Ailey teaching artists Cheryl Rowley-Gaskins and Roderick Johnson. Participants will be led through the dance steps and choreography from three sections of the work. Both workshops include performances by local gospel choirs, and dancers will be accompanied  by live percussion music.
